COLD-CATHODE FIELD EMISSION DEVICE EMPLOYING A CURRENT SOURCE MEANS |
摘要 |
A cold-cathode field emission device controls electron emission by using a current source coupled to the emitter. The open circuit voltage of the current source is less than the voltage at which the FED would emit electrons. Application of an accelerating potential on the gate enables electron emission. Electron emission from the FED is governed by the current source.
